I have a form that has 2 rad comboboxes each bound to its own datasource control.
The second RadCombo's datasource's select parameter takes its value from the SelectdValue of the first RadCombo and then is suposed to supply a new list of items to the second RadCombo.

The second RadCombo also has 1 Static Item and has the AppendDataBoundItems set to "true"

The problem is when I change the selectedInmdex of the first RadCombo and the second RadCombo gets databound, it then Adds the new Items to the second RadCombo instead of replacing them

So as a user clicks and clicks at the different items of the first RadCombo, the list item of the secon Radcombo keep on growing and the items even get duplicated if the same listitem on the first RadCombo gets clicked more than once.

It needs to first clear the list of items before it rebind to the new data.

How do I do this?

<asp:ObjectDataSource ID="ObjectDataSource2" runat="server"

SelectMethod="GetAdSubCats" TypeName="MB.TheBeerHouse.BLL.Ads.AdSubCat">

<asp:ControlParameter ControlID="CatSelect" Name="AdCatID" PropertyName="SelectedValue"

Type="Int32" />

</SelectParameters>

</asp:ObjectDataSource>

<

telerik:RadComboBox ID="SubcatSelect" runat="server"

DataSourceID="ObjectDataSource2" DataTextField="Title" DataValueField="ID"

AppendDataBoundItems="True" AutoPostBack="True" Skin="Hay">

<Items>

<telerik:RadComboBoxItem Text="Select an Ad Heading" Value="0" />

</Items>

</telerik:RadComboBox>

RADControls ASP.NET uninstall issue

Hello,

I've uninstalled ASP.NET AJAX using the program own uninstall shortcut. After the uninstall completed I've noticed that it left entries in windows Add/Remove form. Trying to uninstall again from windows add/remove result in an error 1602. The failed uninstall did remove the entry from the list of installed application so I hope it is uninstalled completly.

Regards,
Tzach

DataBind with HyperLink Column

Hi,

I'm beginning to use RadGrid with a LinqDataSource. The binding of the grid works just fine. Now I want to insert a hyperlink-column into the grid which displays the name of a user and when it's clicked the user's profile page is displayed.

In my aspx file I added the column like this:

<telerik:GridHyperLinkColumn DataTextField="aspnet_User.UserName" HeaderText="User" DataNavigateUrlFields="http://google.de"

SortExpression="aspnet_User" UniqueName="aspnet_User">

</telerik:GridHyperLinkColumn>

Now, the problem is, that there is no text displayed in the grid. It seems that

the DataTextField property is not working (but it is working in a GridBoundColumn).

Another problem is, how to prepare the NavigateUrl property to use the userId.

Edit: I tried to add the GridHyperLinkColumn Programmatically via the RadGrid_ItemDataBound() evend handler but it seems that the handler never

gets called.

Thanks in advance for any hints.

Best regards,

Robert

Date Picker Start of Week

It seems the new date picker that is available does not use the FirstDayOfWeek that is specified on the scheduler, its very confusing to have the scheduler start on Monday but the date picker start on Sunday.

RadTreeView ShowLineImages unexpected behavior

Hello,

I'm using Telerk's ASP.NET AJAX Q2 2008 controls for a project at our firm and I've encountered an unexpected behavior when using the RadTreeView control:
The treeview's ShowLineImages property is set to false and I'm using ServerSideCallback as expand mode for every node in the treeview.
When a node is expanded it is populated with child nodes and it's ExpandMode property is set to ClientSide.
The newly-expanded node is linked to its child nodes with image lines, allthough the treeview's ShowLineImages property is set to false. When a full postback is performed the lines dissapear.
I have followed the coding guide from the RadTreeView documentation when using the treeview control. Is there a posibility that I have missed something or is this a known issue? In case it's a known issue is there a way of correcting it through client-side code?

Thanks,

Adi Muresan

NestedViewTemplate Collapse Problem

Hi,
Just started working on Telerik Controls and was using the RadGrid for a few days now. My Requirement was to show "extra information" in form of Labels and Images in the Grid after a row is collapsed by clicking the "+" or "arrow" icon. I found the following example helpful:

http://demos.telerik.com/aspnet/prometheus/Grid/Examples/Hierarchy/NestedViewTemplate/DefaultCS.aspx

but even if I copy the whole code and test it I cannot collapse an expanded row when I click nothing happens. I tried adding different controls in the NestedViewTemplate and found out that when I place a button there and click it (after expanding), the row collapses. What does that mean? What am I missing here?

Here is my code:

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="myExperiments._Default" %>

RadCalendar appears out of browser boundaries

I have a RadDatePicker in a rtl page, which is close to the right side of the browser.
When the popup button is pressed, the calendar appear from the button towards the right, thus leaving the browser right side. The horizontal scrollbar is activated, but can only scroll left, which doesn't help.
Is there a way to make the calendar appear towards the left?

tnx for any replay.
